properties:
|

name:

type: string
|

description: |
|
||||
Database name (required if using this hook). Or
|
||||
"all" to dump all databases on the host. Note
|
||||
that using this database hook implicitly enables
|
||||
both read_special and one_file_system (see
|
||||
above) to support dump and restore streaming.
|
||||
example: users
|
||||
hostname:
|
||||
type: string
|
||||
description: |
|
||||
Database hostname to connect to. Defaults to
|
||||
connecting to localhost.
|
||||
example: database.example.org
|
||||
port:
|
||||
type: integer
|
||||
description: Port to connect to. Defaults to 27017.
|
||||
example: 27017
|
||||
username:
|
||||
type: string
|
||||
description: |
|

Username with which to connect to the database.
|
||||
Skip it if no authentication is needed.
|

example: dbuser
|

password:
|
||||
type: string
|
||||
description: |
|
||||
Password with which to connect to the database.
|
||||
Skip it if no authentication is needed.
|
||||
example: trustsome1
|
||||
format:
|
||||
type: string
|
||||
enum: ['archive', 'directory']
|
||||
description: |
|
||||
Database dump output format. One of "archive",
|
||||
or "directory". Defaults to "archive" (unlike
|
||||
raw pg_dump). See pg_dump documentation for
|
||||
details. Note that format is ignored when the
|
||||
database name is "all".
|
||||
example: directory
|
||||
options:
|
||||
type: string
|
||||
description: |
|
||||
Additional mongodump options to pass
|
||||
directly to the dump command, without performing
|
||||
any validation on them. See mongodump
|
||||
documentation for details.
|
||||
example: --role=someone
|
||||
description: |
|
||||
List of one or more MongoDB databases to dump before
|
||||
creating a backup, run once per configuration file. The
|
||||
database dumps are added to your source directories at
|
||||
runtime, backed up, and removed afterwards. Requires
|
||||
mongodump/mongorestore commands. See
|
||||
https://docs.mongodb.com/database-tools/mongodump/ and
|
||||
https://docs.mongodb.com/database-tools/mongorestore/ for
